A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.175 kg and moves at v = 5.22 m/s. The circular path has a radius of R = 1.14 m 1.What is the magnitude of the tension in the string when the ball is at the bottom of the circle? 2.What is the magnitude of the tension in the string when the ball is...
A child swings a tennis ball attached to a 0.633-m string in a horizontal circle above his head at a rate of 4.50 rev/s. (a) What is the centripetal acceleration of the tennis ball? (b) The child now increases the length of the string to 1.00 m but has to decrease the rate of rotation to 3.50 rev/s. Is the speed of the ball greater now or when the string was shorter? (c) What is the centripetal acceleration of the...
